6 Claims.

This invention relates to a means for attaching a composite plaster baseto metal supports, and more particularly to a device for fasteninggypsum lath or the like to metal channels for ceiling construction.

There are many types of clips for fastening gypsum lath to metalsupports, but these all have the common fault of supporting the gypsumlath only on the edges and ends. When the first or scratch coat ofplaster is applied over a ceiling erected with clips of the conventionaltype the moisture from the plaster causes a temporary weakening andexpansion of the plaster lath with the result that the lath bowsdownward. This produces a ceiling which has many waves in it which areunsightly and hard to level out. This trouble is particularly prevalentwhen the practice is followed of doubling back with the second coatbefore the first coat has set.

To eliminate the waviness of ceilings which have been applied with anyof the conventional clips we have perfected a nail or device whichfirmly holds the lath to the metal runners so that the lath cannot bow,and at the same time the fastening is flexible enough to allow forexpansion and contraction without causing cracks in the ceiling.

In the accompanying drawing Fig. 1 is a side view of the fastener.

Figs. 2 and 3 are views showing the manner of applying the same.

Fig. 4 is an edge View of the fastener.

Referring now to the attached drawing Fig. 1 shows a View of our nailwhich is made of wire stiff enough to let it be driven through the lathand yet not so stiff that it cannot be readily bent around thesupporting channel iron as shown in Fig. 3. The head of the nail d ispreferably, although not necessarily, 2 inches long. The shank of thenail a is of such a length that it can be driven through the lath b andbent around the channel as shown by the dotted lines in Fig. 3. Theangle between a and d is preferably about 65 but may be varied to meetdifferent conditions without departing from the spirit of thisinvention.

The angle between a and (1 should be great enough so that the nail canbe readily started through the lath as shown in Fig. 2. It may bestarted on either side of the supporting channel 0 and close enough toit so that when the head is brought up flush with the lath the shank ais brought up against one edge of the supporting channel c as shown bythe solid lines a in Fig. 3. The shank a may then be bent by hand orwith a pair of pliers to the position shown by the dotted lines a inFig. 3.

As will be seen when the nail or device is driven in the head part atwill draw up flatly against the lath, as shown in Fig. 3, butnevertheless a certain amount of sliding action is permitted. Theoperation spreads the angle from its original 65 to a. maximum of 90,but leaves a spring action of the angle to hold the lath snugly againstthe metal member. After the application and setting of the plaster thenail is deeply embedded in the mass and is immovable to all prac ticalpurposes. The tie bent around the metal member 0 then becomes the moreflexible of the arms of the nail and will have sufiicient spring andslip to allow for minor movements of setting or expansion andcontraction of the structure, without transferring the movement to theplaster wall, thereby eliminating many cracks which often develop fromthis action.

We claim:

1. The combination with a wall board and supporting member, of afastener comprising a piece of wire bent to form a. penetrating armwhich is driven substantially perpendicularly through the wall board andbent around the supporting memher and another arm normally at an acuteangle to the penetrating arm and which when the latter is driven liessubstantially flat against the surface of the wall board opposite to thesupporting member.

2. A fastener for a wall board or the like, comprising a V-shaped pieceof wire, one arm of which is a penetrating arm adapted to be driventhrough the wall board and bent around a Wall board supporting memberafter such penetration and the other arm of which is an outer or holdingarm, the junction of the two arms having sufficient flexibility topermit them to assume a greater angle when the penetrating arm is sodriven and bent.

3. A fastener for securing a wall board to a supporting membercomprising a piece of spring metal bent at less than a right angle toform two arms, one a penetrating or nail arm adapted to be driventhrough the wall board for engagement with the supporting member and theother a driving or head arm, said arms being located in substantially asingle plane and when driven springing to a greater angularity so thehead arm will lie closely against the wall board into which the otherarm is driven.

4. The combination with a wall board and supporting member, of afastener comprising a. piece of wire bent to form a penetrating armwhich is driven substantially perpendicularly through the wall board andbent around the supporting member, and another arm normally at an acuteangle to the penetrating arm and which when the latter is driven liessubstantially flat against the surface of the wall boardopposite to thesupporting member, both of said arms being located in substantially asingle plane.

5. A wall board construction comprising a supporting member, apenetrable wall board in combination with a resilient securing memberadapted to aflix the wall board to the supporting member, said securingmember V-shaped, consisting of diverging shank portions, one of saidshank portions perforating the wall board at substantially a right angleand having frictional engagement with the surface of the perforation,the other shank portion substantially flat against a face of the wallboard and stressing the firstmentioned shank portion, whereby thesecuring member is aifixed in the penetrable wall board, thefirst-mentioned shank portion deformably afiixed to the supportingmember, the wall board thereby resiliently secured to the supportingmember by virtue of the stress imparted to the securing member.

6. As an article of manufacture, a securing l member adapted forerecting penetrable. wall-V a substantially straight elongated resilientmetal member distorted 'to provide divergent shanks ,extending at anacute angle one with respect to the other from a common apex, with thedivergent shanks lying in substantially the same plane diverging onefrom another at an angularity of the order of 65, one of said shanksadapted to be forced through a wallboard at substantially right anglesto the face thereof and have its outer end secured to a supportingmember whereby the wallboard may be mounted between the other divergingshank and the supporting member.
